Outline the role of the following organelles in the synthesis and transport of molecules:
a)ribosomes
b)endoplasmic reticulum
c)Golgi Apparatus
d)vesicles


And also this Qs

What is the role of mitochondria in the synthesis of molecules??
 
ribosoms: they are used to synthesize proteins by "reading" the genetic code from a m-RNA (messenger RNA). a ribosome consists of two halves, that clutch the m-RNA to "read" it.

ER: The endoplsmatic reiculum is a system of "tunnels" to transport proteins and to fold proteins.

Golgi apparatus+ vesicles: it produces vesicles that carry different porteins within the cell. Vesicles are used eg to transport neurotransmitters at the synapses

hope I could help you a little ;-)
